IS CAPM A GOOD PREDICTOR OF STOCK RETURN IN NIGERIAN BUILDING MATERIALS SECTOR STOCKS?

Abstract

This research is on testing the predictive power of Capital Asset Pricing Model (CAPM) as enunciated by Sharpe (1964) in the determination of the required rates of return of Nigerian Building Materials stocks that coincides with the actual rates of return. As it were, there is no clear cut understanding on the belief with particular reference to Nigerian Building Materials stocks. In the light of the above assertion, the objective of this study is to find out the required rate of return of Nigerian Building Materials stocks from 2000-2012 and compare them with the actual rates of return in the corresponding periods to indentify the valuation status of the stocks. Being an empirical study, analytical research design was adopted. The data used were secondary data, which were collected from the financial statements of the subject-firms, Nigerian Stock Exchange publications, and Central banks of Nigeria publications. The study reveals that the Capital Asset Pricing Model (CAPM) as enunciated by Sharpe (1964) is not a good predictor of stock return in the Building Materials sector of the Nigerian Stock Exchange.
